Pet Peeves

I have two major pet peeves. And it probably stems from growing up in a family of people that are English majors. Okay, no one in my family is an English major, but it sure seems like it. And it seems more so like that lately. I hate hate hate people that use bad grammar. I just want to yell and scream and jump up and down (no, not that bad) and correct them. I think it's most aggravating when it's someone I don't know. I have no problem correcting my friends on their grammar. One of the ladies I used to work with at my t-comm job always asked customers, "Do you have a number where I can call you back at?" Yeah, it's improper grammar. NEVER EVER end a sentence with a preposition. You either don't put the "at" at the end of the sentence, or find someplace else to put it. "I don't have no..." is another of those that drives me crazy. I mean, really really crazy. To the point of actually yelling. Even if it's someone I don't know. I just want to tell them to go back to school and learn the English language...which is not a very easy language to learn.
Bad spelling makes me insane, too. I guess it's because I've always been an excellent speller, and people that don't know how, well it just bugs me. I just read something on my work website talking about their insurance cards but "their" was spelled "there." It's a common mistake I know, and I've been known (just once) to make that mistake. But COME ON!!! Stop and think about it before you type or write the damn word! Or maybe it's a grammar mistake? Either way...
And no, I'm not some snobby smarty pants that'll call you out on your misspellings if I see them. I'm not that much of a Nazi about it all. It's just aggravating, that's all. It's just one of my little quirks I acquired while growing up with my family.
